摘要： A component incorporating a dielectric element such as a polymeric film with leads and terminals thereon is assembled with a semiconductor chip and bond regions of the leads are connected to contacts of the chip. At least one lead incorporates a plural set of connecting regions connecting the bond region of that lead to a plurality of terminals. One or more of the connecting regions in each such plural set are severed so as to leave less than all of the terminals associated with each such plural set connected to the contacts of the chip.

摘要： The present invention provides a method for fabricating a compliant microelectronic device package and an associated apparatus for substantially obviating thermal, compliancy and interconnection problems. Flexible, dielectric layers are used having on a first surface a plurality conductive leads which are each electrically coupled at a first end to at least one conductive pad also coupled to the first surface of the dielectric layers. A second end of the conductive leads are further coupled between the dielectric layers across a bonding gap. A compliant layer is then coupled to the bottom surface of the dielectric layers. One of the dielectric layers is coupled to the surface of a die by one of the compliant layer such that the die bond pads are juxtaposed with respective leads in the bonding gap. This assembly is attached to a protective structure and is encapsulated. A solder mask may be placed over the exposed surface of the dielectric layers to cover the leads and prevent shoring. Further, a conductive layer may be used in the package as a ground layer of a voltage reference layer.

摘要： The present invention provides an interconnection scheme having complaint contacts arranged in an array to connect conductive surfaces on a microelectronic device and a supporting substrate, such as a printed circuit board. This invention accommodates for the difference in thermal coefficients of expansion between the device and the supporting substrate. Typically, an area array of conductive contact pads are connected into rows by conductive leads on a flexible, intermediate substrate. Each of the conductive leads bridges a bonding hole in the intermediate substrate which is situated between successive contact pads. Each of the conductive leads further has a frangible portion within or near each bonding hole. A stand-off between the intermediate substrate and the device is create by compliant dielectric pads, typically composed of an elastomer material, positioned under each contact pad. The frangible portions allow the leads to be cleanly broken, bent and secured into electrical contact with chip contacts on the device. Each of these connections may be supported by a compliant layer, typically an uncured elastomer which fills the area around the compliant dielectric pads and is then cured.

摘要： A semiconductor chip connection component having numerous leads extending side-by-side across a gap in a support structure, each lead having a frangible section to permit detachment of one end of the lead from the support structure in a bonding process. The frangible sections are formed by treating the lead-forming material in an elongated treatment zone extending across the regions occupied by numerous leads. The process avoids the need for especially fine etching to form notches in the lateral edges of the leads.

摘要： A connection component for use in making microelectronic element assemblies which has peelable leads that are formed on a dielectric support structure. One end of each lead is permanently connected to the support structure and the opposite end of the lead is releasably connected to the support structure. When the releasable end of the lead is bonded to a contact on a semiconductor chip, the releasable end of the lead can be peeled from the support structure such that the chip may be moved away from the support structure. A compliant layer may be disposed between the chip and the support structure. If a compliant material is injected between the chip and the support structure to form the compliant layer, the compliant material will lift the chip away from the support structure and facilitate the peeling of the leads from the support structure.

摘要： A method of manufacturing a plurality of semiconductor chips packages and the resulting chip package assemblies. The method includes providing a circuitized substrate having terminals and leads. A spacer layer is deposited or attached to the substrate and each chip is then attached to the spacer layer. The leads interconnect contacts on the chip to the terminals on the substrate wherein at least some of the terminals lie outside the periphery of the chip. Typically, the spacer layer is comprised of a compliant or resilient material. A curable encapsulant material is deposited so as to encapsulate the leads and at least one surface of the chip. A unitary support structure is then aligned and attached to the encapsulant around the edges of the chips. The encapsulant material is then cured thereby defining a composite of chip assemblies which may be singulated into individual chip packages.

摘要： A method of treating a lead in a chip package. A conductive lead is positioned such that it extends across a gap in a dielectric substrate and is secured at either end to a first surface of the substrate. Directed energy is then applied to a desired portion of the surface of the lead within the gap. As a result of the application of energy, a surface layer of the lead is recrystallized thereby creating a fine grain, dense surface layer of lead material. Surface contaminates may be vaporized and contaminants at the grain boundaries of the recrystallized surface layers may be driven away from the grain boundaries such that a treated lead is more ductile and has better resistance to thermal cycling after the lead has been attached to a chip contact.
